摘　　要：A novel compound [(IBz)2Im](TCNQ) [(IBz)2Im=1,3-bis(4-iodobenzyl) imidazole cation, TCNQ-=7,7,8,8-tetracyanoquinodimethanide anion] was synthesized by the reaction of [(IBz)2Im]Br and LiTCNQ in CH3OH and its structure was determined by single-crystal X-ray diffraction. The crystal belongs to monoclinic, space group P21/c with a=1.147 35(18) nm, b=2.028 1(3) nm, c=1.264 1(2) nm, β=104.73(0)°, V=2.666(65) nm3, Z=4, C29H19I2N6, Mr= 705.30, Dc=1.757 g·cm-3, R1=0.053 2 and wR2=0.111 2. The structure analysis shows that the anions are stacked into column with isolated π-dimers, and there is one type of TCNQ entries (TCNQ-), in agreement with the IR spectra analysis of the compound. The most prominent structural features are the completely segregated stacking columns of the TCNQ-anions and [(IBz)2Im]+ cations. CCDC: 759523.A novel compound [（IBz）2Im]（TCNQ） [（IBz）2Im=1,3-bis（4-iodobenzyl） imidazole cation, TCNQ-=7,7,8,8-tetracyanoquinodimethanide anion] was synthesized by the reaction of [（IBz）2Im]Br and LiTCNQ in CH3OH and its structure was determined by single-crystal X-ray diffraction.
